In prior years, the TTX extension forms require foreign residents to file the extension by mail, since the TTX form didn't allow foreign addresses. I personally have no idea if the TTX form 4868 allows foreign addresses this year....but if it doesn't, the link to the IRS form is shown below. Fill it out and mail it to the IRS...use some kind of local mail tracking/registration as proof you filed it on time. You will still have the same October 15 deadline as everyone else.
